DETAILED DESCRIPTION OF NON-LIMITING EXAMPLE EMBODIMENTS

Hereinafter, embodiments of the present invention will be described withreference to the accompanying drawings. Further, embodiments to bedescribed below are merely examples for carrying out the presentinvention, and the present invention is not limited to a specificconfiguration to be described below. When the present invention iscarried out, a concrete configuration according to an embodiment may beappropriately employed.

A first embodiment relates to an inspection system and an inspectingdevice which are capable of inspecting a gaming chip, and moreparticularly to, an inspection system and an inspecting device which arecapable of inspecting a plurality of gaming chips contained in a case.

Gaming chips used in game halls such as casinos are manufactured infactories and then transported to game halls, stored in a storage, andmoved from the storage to cashiers or game tables in the hall, but it isnecessary to prevent gaming chips from being stolen or being replacedwith fake gaming chips in the process of transporting, storing, andmoving. To this end, a case containing gaming chips is used. If aplurality of gaming chips are contained in the case and, then the caseis sealed, it is possible to discover a situation in which the gamingchips are withdrawn from the case after the sealing.

As a gaming chip in which a radio tag storing identification informationor type information is internally installed, and optically readable codeinformation indicating the identification information or the typeinformation is assigned to a side surface is known (for example, JP2009-66172 A).

A system using a gaming chip is disclosed in JP 2009-66172 A. In thesystem, the number of gaming chips placed on a betting board of a gametable is calculated on the basis of identification information stored ina radio tag, the number of gaming chips is calculated on the basis ofidentification information assigned to a side surface, and thecalculated numbers of gaming chips are compared. Accordingly, it ispossible to detect an unauthorized gaming chip when the unauthorizedgaming chip is used in the game table.

However, since the system disclosed in JP 2009-66172 A detects a fraudby calculating the number of bet gaming chips (placed on the bettingboard), the system is unable to inspect a plurality of gaming chipscontained in the case in a state where the gaming chips are contained inthe case and detect the unauthorized gaming chip.

In this regard, it is an object of the first embodiment to provide aninspection system and an inspecting device which are capable ofinspecting a plurality of gaming chips contained in a case in a statewhere the gaming chips are contained in the case.

An inspection system according to a first aspect of the first embodimentis an inspection system that inspects a gaming chip having at leastfirst gaming chip information and second gaming chip information, thesecond gaming chip information is arranged on a side surface of thegaming chip in an optically readable form, the inspection systemincludes a case that contains a plurality of gaming chips in a stackedmanner and an inspecting device that inspects the gaming chip containedin the case, wherein the inspecting device includes a first readingdevice that acquires the first gaming chip information of the gamingchip contained in the case, a second reading device that optically readsthe side surface of the gaming chip contained in the case and acquiresthe second gaming chip information, and a determining unit thatdetermines whether a plurality of gaming chips contained in the case arepass or fail by determining the authenticity or damages of all thegaming chips contained the case or the number of gaming chips for eachvalue using the first gaming chip information acquired by the firstreading device and the second gaming chip information acquired by thesecond reading device.

With this configuration, since both the first reading unit and thesecond reading unit acquire the first gaming chip information and thesecond gaming chip information from the gaming chip contained in thecase, it is possible to inspect the gaming chips contained in the case.Further, since two pieces of information, that is, the first gaming chipinformation and the second gaming chip information are acquired from thegaming chip, and the inspection is performed, the pass/faildetermination can be reliably performed.

In an inspection system according to a second aspect of the firstembodiment, in the inspection system of the first aspect, the firstgaming chip information and the second gaming chip information in acommon gaming chip include common information, and the determining unitdetermines that a plurality of gaming chips contained in the case arefail when common information portions of a plurality of pieces of firstgaming chip information acquired by the first reading device do notcoincide with common information portions of a plurality of pieces ofsecond gaming chip information acquired by the second reading device.

With this configuration, when an unauthorized gaming chip in which thecommon information portion of the first gaming chip information does notcoincide with the common information portion of the second gaming chipinformation is contained in the case, the determining unit can determinethat the gaming chips contained in the case are fail.

For example, when common identification information is recorded in theradio tag and the side surface, fail is determined if a plurality ofpieces of identification information read out from a plurality of radiotags do not coincide completely with a plurality of pieces ofidentification information read out from a plurality of side surfaces.Further, when a value of the gaming chip is recorded in the radio tagand the side surface, fail is determined if the number of each valueread from the radio tag does not coincide with the number of each valueread from the side surface.

In an inspection system according to a third aspect of the firstembodiment, in the inspection system of the first aspect, both or eitherof the first gaming chip information and the second gaming chipinformation includes individual identification information individuallyidentifying the gaming chip.

In an inspection system according to a fourth aspect of the firstembodiment, in the inspection system of the first aspect, the secondgaming chip information includes information indicated by a designatedcolor indicating the value of the gaming chip and is informationindicating the value of the gaming chip through the designated color.

In an inspection system according to a fifth aspect of the firstembodiment, in the inspection system of the third aspect, both the firstgaming chip information and the second gaming chip information includeindividual identification information, and a plurality of gaming chipscontained in the case are determined to be fail when the individualidentification information of a plurality of pieces of first gaming chipinformation acquired by the first reading device does not coincide withthe individual identification information of a plurality of pieces ofsecond gaming chip information acquired by the second reading device.

With this configuration, when an unauthorized gaming chip in which theindividual identification information of the first gaming chipinformation does not coincide with the individual identificationinformation of the second gaming chip information is contained in thecase, the determining unit determines that the gaming chips contained inthe case are fail.

In the inspection system of the first aspect, an inspection systemaccording to a sixth aspect of the first embodiment includes a storageunit that stores the individual identification information of at leastthe first gaming chip information or the second gaming chip informationof a plurality of gaming chips to be contained in the case, and thedetermining unit determines that a plurality of gaming chips containedin the case are fail when the individual identification information of aplurality of pieces of first gaming chip information acquired by thefirst reading device or a plurality of pieces of second gaming chipinformation acquired by the second reading device does not coincide withthe individual identification information of the first gaming chipinformation or the second gaming chip information stored in the storageunit.

<Structure of Gaming Chip>

FIG. 2 is a perspective view of the gaming chip C according to anembodiment of the present invention, and FIG. 3 is a side view of thegaming chip C according to an embodiment of the present invention. Thegaming chip C has a designated color layer 501 which is characterized bya designated color in the middle and a common color layer 502 which ischaracterized by a common color on both sides of the designated colorlayer 501 in the middle in a thickness direction (upper and lower sidesin FIG. 3 ), and a stripe pattern (in the thickness direction) is formedon the side surface.

An RFID tag 503 is inserted between the designated color layer 501 andone common color layer 502 of the gaming chip C as a radio tag. Forexample, individual identification information individually identifying(uniquely specifying) the gaming chip C and value (type) information arestored in the RFID tag 503 as the gaming chip information of the gamingchip C. A transparent layer 504 is formed as the outermost layer of thegaming chip C. In other words, the gaming chip C includes the designatedcolor layer 501 which is an intermediate layer, the common color layers502 sandwiching the designated color layer 501 from both sides, and thetransparent layers 504 which are the outermost layers of both sides.

The gaming chip C is formed such that five elongated layers of plasticmaterials (the transparent layer 504, the common color layer 502, thedesignated color layer 501, the common color layer 502, and thetransparent layer 504) are stacked, the RFID tag 503 is arranged betweenthe designated color layer 501 and one common color layer 502 at apredetermined interval at that time, and the five layers of plasticmaterials are thermocompression bonded and then punched into a circularshape, a rectangular shape, or the like through a press so that one RFIDtag 503 is included in one gaming chip C. When the punching is performedthrough the press, dimensions of a die and a punch of a mold forpunching are designed, and R treatment (rounded corner) is applied tothe end of the transparent layer 504 of the outermost layer.

The transparent layer 504 may be formed by thermocompression bondingthree layers including the designated color layer 501 and the two commoncolor layers 502 and then applying varnish to the surface. Further, thedesignated color layer 501 and the two common color layers 502 may notbe separate members, and the designated color layer 501 and the twocommon color layers 502 may be formed by applying the designated color(and the common color) to the side surface through inkjet printing orthe like after the designated color layer 501 and the two common colorlayers 502 are integrally formed.

The designated color layer 501 indicates the value (type) of the gamingchip C using a color (a designated color). In other words, the color ofthe designated color layer 501 is set to a different color (red, green,yellow, blue, or the like) in accordance with the value of the gamingchip C, and thus it is possible to specify the value of the gaming chipC (10 points, 20 points, 100 points, 1000 points, or the like) bychecking the color of the designated color layer 501 optically read fromthe side surface of the gaming chip C. A color common to the gamingchips C having different values (a common color) is assigned to thecommon color layer 502. The common color is preferably a color lighterthan any designated color, and the common color is white in the presentembodiment.

Code information 505 indicating the gaming chip information of thegaming chip C is further inscribed on the side surface of the gamingchip C (specifically, the common color layer 502 of the side surface).The code information 505 indicates information by arranging a pluralityof marks (square marks in the present embodiment). Since the designatedcolor layer 501 indicates information (the value of the gaming chip C)with color, whereas the code information 505 indicates information witha mark inscribed on the side surface, the code information 505 can beregarded as notation information. Examples of the notation informationinclude a plurality of character strings, a numeric string, and a barcode.

The code information 505 of the present embodiment is repeatedlyinscribed with a cycle of 60° in a circumferential direction of thegaming chip C. Accordingly, the perfect code information 505 is includedwithin a range of 120° in the circumferential direction regardless of adirection in which the side surface of the gaming chip C is observed inthe circumferential direction. A repetition cycle of the gaming chip Cis not limited to 60° and may be repeatedly inscribed at equal intervalsin the circumferential direction at least three times.

The code information 505 is inscribed using invisible ink. In thepresent embodiment, printing is performed by inkjet printing usinginfrared absorbing ink (specifically, carbon black) that absorbsinfrared rays as the invisible ink. Since only a portion on which thecode information 505 is printed does not reflect infrared rays, the codeinformation 505 floats when the side surface of the gaming chip C isphotographed by the infrared camera 225. In order to cause the printedportion to float clearly, the infrared camera 225 may be equipped withan infrared lamp and irradiate the side surface of the gaming chip C tobe photographed with infrared rays.

Further, the invisible ink is not limited to the infrared absorbing inkand may be, for example, infrared reaction ink that emits fluorescencein response to infrared rays or UV ink which emits fluorescence inresponse to ultraviolet rays. In the case of using the UV ink, theultraviolet camera is used in place of the infrared camera 225, andblack light which irradiates the side surface of the gaming chip C withultraviolet rays is used to cause the UV ink to emit fluorescence.

Further, in the gaming chip C, a mark m′ using the UV ink or the carbonblack ink is formed on a surface X of the common color layer 502. Themark m′ indicates whether the gaming chip 5 is true or false, and themark m′ becomes visible when irradiated with ultraviolet rays (orinfrared rays), and it is indicated whether the gaming chip 5 is true orfalse in accordance with a combination of shapes of the mark m′ and thenumber of marks m′. The transparent layer 504 is thermocompressionbonded or applied on the outermost layer so as to cover a print 506(such as 100 points) for specifying the game hall or the mark m′ on thesurface, but embossing treatment or vanish treatment is applied to thetransparent layer 504, and thus the gaming chips C are prevented fromadhering to each other, and slipping is further improved.

The R treatment (R) is performed on the end of the transparent layer 504of the outermost layer which has undergone a print 506 (100 points orthe like), and the surface of the common color layer 502 is preventedfrom being deformed in the process of punching the gaming chip C andappearing on the side surface. Further, a sharp edge of the gaming chipC is prevented from remaining and damaging a hand and other gaming chipsC. The designated color layer 501 may be formed by one or a plurality ofcolored layers. Further, metal or ceramics for increasing the weight ofthe layer may be formed in the layer of the designated color layer 501.Further, the RFID tag 503 may be installed in a space which is formed ina part of the designated color layer 501 or between the designated colorlayer 501 and the common color layer 502.

FIG. 4 is a diagram illustrating an example of an image obtained byphotographing a plurality of gaming chips C contained in the case 100through the infrared camera 225 and the visible light camera 226. Inthis case, the case 100 may be a two-stage chip float (an upper trayportion which is particularly movable in a two-stage chip tray) or achip tray which holds the gaming chip C in the game table. Even when thegaming chip C is stacked in the case 100 in the vertical direction asillustrated in FIG. 4 , the infrared camera 225 and the visible lightcamera 226 can photograph the code information 505. Further, it ispossible to count the number of gaming chips C by counting thedesignated color layer 501 in the vertical direction. Even with thetwo-stage tray, when each stage is developed, it is possible to capturethe side surfaces of all the gaming chips C contained in the case 100through the infrared camera 225 and the visible light camera 226.

In the present embodiment, the code information 505 is indicated by themarks m arranged in a plurality of rows and a plurality of columns. FIG.5 is a diagram for describing a configuration of the code information505. As illustrated in FIG. 5 , upper and lower marks m are paired toform one code element. In the example of FIG. 5 , one piece of codeinformation 505 is configured with a 10-digit code element. There arefour types of patterns of one code element constituted by a pair ofupper and lower marks m, four types of information can be indicated byone code element as illustrated in FIG. 5 , and thus the codeinformation 505 configured with the 10-digit code element can indicate10-th power of 4 types of information. A character Y on the side of the10-digit code element is a direction determination mark Y fordetermining the direction of the code information 505.

FIG. 6 is a block diagram illustrating a configuration of the inspectingdevice 200. The inspecting device 200 includes a bar code reader 228 anda communication unit 229 in addition to the RFID reader 221, thecomputer 222, the display unit 223, the RFID antenna 224, the infraredcamera 225, and the visible light camera 226 illustrated in FIG. 1 .Further, the computer 222 is configured with a processor (notillustrated), a memory, and the like and functions as an identifyingunit 230 and a determining unit 231 when the processor executes aninspection program.

An RFID system is configured with the RFID reader 221, the RFID antenna224, and the RFID tag 503 embedded in the gaming chip C. The gaming chipinformation of the gaming chip C stored in the RFID tag 503 embedded inthe gaming chip C is read out by the RFID reader 221 in a non-contactmanner and used for a process in the computer 222.

The infrared camera 225 includes an infrared transmission filter thattransmits only infrared light and captures an infrared image. Theinfrared image generated by the photographing of the infrared camera 225is transmitted to the computer 222 and used for a process of theidentifying unit 230. The visible light camera 226 captures an image oflight of a visible region. A visible light image generated by thephotographing of the visible light camera 226 is also transmitted to thecomputer 222 and used for a process of the identifying unit 230. Asillustrated in FIG. 1 , the infrared camera 225 and the visible lightcamera 226 are directed toward the case 100 above the case 100, andphotograph the side surfaces of a plurality of gaming chips C in thecase 100 over the upper portion 101 of the case 100.

The bar code reader 228 reads the bar code BC attached to the case 100and acquires case identification information to be described later. Thedisplay unit 223 displays a determination result of the determining unit231 of the computer 222. The communication unit 229 communicates datawith a manufacturing management device 302 installed in a factory F or ause management device 303 installed in a game hall P.

FIG. 7 is a perspective view of a case 100. The case 100 is formed bycombining the upper portion 101 and the lower portion 102. In thepresent embodiment, the upper portion 101 and the lower portion 102 aremade of transparent resin. As described above, since the infrared camera225 and the visible light camera 226 of the inspecting device 200 of thepresent embodiment (hereinafter referred to simply as a “camera”)installed above the receiving unit 210, it is necessary for at least theupper surface of the case 100 to transmit light. In other words, in thecase 100, a portion positioned between the receiving unit 210 of theinspecting device 200 and the camera when the case 100 is received bythe receiving unit 210 of the inspecting device 200 needs to be a lighttransmitting portion. In the present embodiment, the case 100 has asealed structure including the upper portion 101 and the lower portion102, but the light transmission portion may be in a perforated state.

As described above, the case 100 has a shape in which the five columnsin which 20 gaming chips C are stacked and contained are formed inparallel, and in the example of FIG. 7 , a cross section of each columnis polygonal (octagonal) so that the upper portion 101 and the lowerportion 102 substantially follow the shape of the gaming chip C to becontained.

FIG. 8 is a perspective view of a case 100′ according to a modifiedexample, and FIG. 9 is a plan view of the case 100′. The case 100′ alsoincludes an upper portion 101′ and a lower portion 102 made of atransparent resin. In the present modified example, the upper surface ofthe upper portion 101′ facing the camera is formed as a plane surface.Since the surface facing the camera is a plane surface, a linear shadowcaused by a corner of a polygon cross section of the case 100′ does notappear on the camera as illustrated in FIG. 9 , and it is possible toaccurately identify information of the side surface of the gaming chip Cin image analysis on a captured image of the camera.

FIG. 10 is a diagram for describing an example of a use state of theinspection system 1 together with the distribution of the gaming chipsC. The gaming chip C is manufactured by a manufacturing device 301 of afactory F (s1), and 100 gaming chips C are contained in the case 100(s2). The case 100 is sealed with a seal at the factory F after thegaming chips C are contained. Further, the bar code BC indicating thecase identification information uniquely specifying the case 100 isaffixed to the side surface of the case 100 (s3).

At this time, the case identification information of the bar code BCaffixed to the case 100 is input to the manufacturing management device302 in the factory F (s4). Further, the case 100 containing the gamingchips C is transferred to the inspecting device 200, the gaming chipinformation (to be described later in detail) assigned to the gamingchip C is read, and the pass/fail inspection is performed. The gamingchip information read from the gaming chip C contained in the case 100is transferred to the manufacturing management device 302 (s5) andassociated with the case identification information through themanufacturing management device 302. The manufacturing management device302 may be a personal computer.

The case 100 determined to be pass in the inspecting device 200 of thefactory F is conveyed from the factory F to a game hall P (s6). The case100 is first stored in a storage R in the game hall P (s7). Theinspecting device 200 is installed in the storage R, and the case 100that arrived from the factory F is inspected through the inspectingdevice 200.

Meanwhile, the case identification information and the gaming chipinformation associated with the case identification information aretransmitted from the manufacturing management device 302 in the factoryF to the use management device 303 in the game hall P. The usemanagement device 303 acquires the case identification information andthe gaming chip information associated with the case identificationinformation from the manufacturing management device 302 for each of aplurality of cases 100 containing the gaming chip C and includes astorage unit that stores the acquired information for each case 100. Theuse management device 303 may be a personal computer.

In the inspection performed by the inspecting device 200 in the storageR, an inspection is performed using the information stored in the usemanagement device 303. The case 100 determined to be pass in theinspection in the storage R is carried to a game table T (s9) or carriedto a cashier CA (s10). Each of the game table T and the cashier CAincludes the inspecting device 200, and the case 100 containing thegaming chip C is inspected by the inspecting devices 200 in a sealedstate. In the game table T and the cashier CA, the case 100 containingused gaming chips C is also inspected, and the inspecting device 200 isalso used for the inspection. In the inspection in the three inspectingdevices 200 in the game hall P, the case identification informationtransmitted from the manufacturing management device 302 and stored inthe use management device 303 and the gaming chip information associatedwith the case identification information are referred to.

FIG. 11 is a diagram illustrating an example of content of informationwhich is generated by the manufacturing management device 302,transmitted to the use management device 303, and stored in the usemanagement device 303. Information is generated for each case 100, andthe gaming chip information of a plurality of gaming chips C (100 gamingchips in the present embodiment) contained in the case 100 is associatedwith each piece of case identification information (Ca1, Ca2, Ca3, . . .).

As the gaming chip information, information including a combination ofthe individual identification information (aa, ab, ac, . . . , du, dv)uniquely specifying the gaming chip C and information (r, r, r, b, b)specifying the value (type) of the gaming chip C is stored in the RFIDtag 503, information including a combination of individualidentification information (00001, 00002, 00003, . . . , 00099, 00100)uniquely specifying the gaming chip C and information (1, 1, 1, . . . ,2, 2) specifying the value (type) of the gaming chip is stored as thenotation information of the side surface, and information (red, red,red, . . . , blue, blue) specifying the value (type) of the gaming chipC is stored as the color information of the side surface.

The information stored in the RFID tag 503 is information which iselectromagnetically readable by the RFID reader 221 and corresponds tofirst gaming chip information of the present invention, and the notationinformation assigned to the side surface and the color information areoptically readable information and correspond to second gaming chipinformation of the present invention.

FIG. 12 is a diagram illustrating an example of content of informationacquired from one case 100 through the bar code reader 228, the RFIDreader 221, the infrared camera 225, and the visible light camera 226 inthe inspecting device 200. An English character string stored in theRFID tag 503 installed in each of a plurality of gaming chips C is readout from the RFID reader 221. A numeric string which is the notationinformation inscribed on the side surface is read out from the infraredcamera 225. Further, the color of the side surface is read out from thevisible light camera 226. The identifying unit 230 analyzes (the imageof) the numeric string read out from the infrared camera 225, identifiesa number, specifies information including the numeric string, andspecifies the designated color from the image of the side surface readout from the visible light camera 226.

Here, the notation information and the designated color information ofthe side surface of a plurality of gaming chips C can be acquired inaccordance with an arrangement order of the gaming chips C in the case100, but the information acquired from a plurality of RFID tags 503 isunable to be acquired in accordance with the arrangement order of thegaming chips C. In other words, it is difficult to specify a gaming chipC from which the information of the RFID tag 503 is obtained.

Next, a pass/fail determination method in the computer 222 of theinspecting device 200 will be described. As described above, theidentifying unit 230 specifies the gaming chip information stored in theRFID tags 503 of each of a plurality of gaming chips C contained in thecase 100 on the basis of a result of reading the RFID reader 221,analyzes the infrared image obtained by the infrared camera 225,specifies the gaming chip information indicated by the notationinformation, analyzes the visible light image obtained by the visiblelight camera 226, and specifies the color of the designated color layer501. On the basis of the information, the determining unit 231determines the authenticity/damage of all the gaming chips contained inthe case or the number of gaming chips of each value on the basis of theinformation, and determines whether the case 100 is pass or fail. In thefollowing description, the gaming chip information stored in the RFIDtag 503 is referred to as “first gaming chip information”, and thenotation information assigned to the side surface of the gaming chip Cand the color information of the designated color layer 501 are referredto as “second gaming chip information.”

In a first pass/fail determination method, the first gaming chipinformation and the second gaming chip information in the same gamingchip are the same information as illustrated in FIG. 13 . In an exampleof FIG. 13 , the first gaming chip information is information includingthe individual identification information and the value information ofeach gaming chip C, and the same content as the first gaming chipinformation is inscribed on the side surface in a form of the notationinformation as the second gaming chip information.

The RFID reader 221 reads the first gaming chip information from theRFID tag 503 of the gaming chip C and outputs the first gaming chipinformation to the identifying unit 230, the infrared camera 225photographs the side surface of the gaming chip C, and the identifyingunit 230 specifies the second gaming chip information. In this case, inthe identifying unit 230, a correspondence relation between a pluralityof pieces of first gaming chip information and a plurality of pieces ofsecond gaming chip information is unclear.

The determining unit 231 compares a plurality of pieces of first gamingchip information obtained by the identifying unit 230 with a pluralityof pieces of second gaming chip information, and when a plurality ofpieces of first gaming chip information completely correspond to aplurality of pieces of second gaming chip information in a one-to-onemanner, that is, when all pieces of first gaming chip informationcoincide with any one of second gaming chip information withoutoverlapping, the determining unit 231 determines that a plurality ofgaming chips C contained in the case 100 are pass, but when a pluralityof pieces of first gaming chip information obtained by the identifyingunit 230 do not completely coincide with a plurality of pieces of secondgaming chip information, the determining unit 231 determines that aplurality of gaming chips C contained in the case 100 are fail.

As a case in which a plurality of pieces of first gaming chipinformation obtained by the identifying unit 230 do not completelycoincide with a plurality of pieces of second gaming chip information,there is a case in which any one of the gaming chips C contained in thecase 100 is a fake or a case in which the RFID tag 503 or the sidesurface of the gaming chip C is damaged. In other words, the determiningunit 231 determines whether a plurality of gaming chips C contained inthe case 100 are pass or fail by determining the authenticity/damage ofall the gaming chips contained in the case 100.

In a second pass/fail determination method, the first gaming chipinformation and the second gaming chip information in the same gamingchip C are the same information as illustrated in FIG. 14 . In anexample of FIG. 14 , the first gaming chip information is the valueinformation of each gaming chip C, and in each gaming chip C, thedesignated color is assigned to the designated color layer 501 of theside surface as the second gaming chip information.

The RFID reader 221 reads out the first gaming chip information from theRFID tag 503 of the gaming chip C and outputs the first gaming chipinformation to the identifying unit 230, the visible light camera 226photographs the side surface of the gaming chip C, and the identifyingunit 230 analyzes the image and specifies the second gaming chipinformation (the color of the designated color layer 501).

In this case, in the identifying unit 230, a correspondence relationbetween a plurality of pieces of first gaming chip information and aplurality of pieces of second gaming chip information is unclear, aplurality of pieces of first gaming chip information may overlap eachother, and a plurality of pieces of second gaming chip information mayalso overlap with each other. In the first gaming chip information andthe second gaming chip information of FIG. 14 , “r” indicates red, “b”indicates blue, “y” indicates yellow, and “g” indicates green.

When the number of each of all the designated colors (red, blue, yellow,and green) in a plurality of pieces of first gaming chip informationobtained by the identifying unit 230 coincides with the number of eachof all the designated colors (red, blue, yellow, and green) in aplurality of pieces of second gaming chip information, the determiningunit 231 determines “pass,” and otherwise, the determining unit 231determines “fail.”

As a case in which the number of each of all the designated colors inthe first gaming chip information does not coincide with the number ofeach of all the designated colors in a plurality of pieces of secondgaming chip information, there is a case in which any one of the gamingchips C contained in the case 100 is a fake or a case in which the sidesurface of any of the gaming chips C is damaged. In other words, thedetermining unit 231 determines whether a plurality of gaming chips Ccontained in the case 100 are pass or fail by determining the number ofall the gaming chips C contained in the case 100 for each value.

In a third pass/fail determination method, the first gaming chipinformation and the second gaming chip information in the same gamingchip C are different information as illustrated in FIG. 15 . In anexample of FIG. 15 , information of an English character string isstored in the RFID tag 503 of the gaming chip C as the first gaming chipinformation, and the notation information of a numeric string isinscribed on the side surface of the gaming chip C as the second gamingchip information.

The RFID reader 221 reads out the first gaming chip information from theRFID tag 503 of the gaming chip C and outputs the first gaming chipinformation to the identifying unit 230, the infrared camera 225photographs the side surface of the gaming chip C, and the identifyingunit 230 specifies the second gaming chip information. In this case, inthe identifying unit 230, a correspondence relation between a pluralityof pieces of first gaming chip information and a plurality of pieces ofsecond gaming chip information is unclear.

The first gaming chip information and the second gaming chip informationare stored in the use management device 303 in association with the caseidentification information of the case 100. The determining unit 231compares a plurality of pieces of first gaming chip information obtainedby the identifying unit 230 with a plurality of pieces of first gamingchip information associated with the case identification information ofthe case 100 stored in the use management device 303, and determineswhether or not they completely correspond to each other in a one-to-onemanner. The determining unit 231 compares a plurality of pieces ofsecond gaming chip information obtained by the identifying unit 230 witha plurality of pieces of second gaming chip information associated withthe case identification information of the case 100 stored in the usemanagement device 303 and determines whether or not they completelycorrespond to each other in a one-to-one manner.

When a plurality of pieces of first gaming chip information obtained bythe identifying unit 230 completely correspond to a plurality of piecesof first gaming chip information associated with the case identificationinformation of the case 100 stored in the use management device 303 in aone-to-one manner, that is, a plurality of pieces of first gaming chipinformation obtained by the identifying unit 230 coincide with any oneof a plurality of pieces of first gaming chip information associatedwith the case identification information of the case 100 stored in theuse management device 303 without overlapping, and a plurality of piecesof second gaming chip information obtained by the identifying unit 230completely correspond to a plurality of pieces of second gaming chipinformation associated with the case identification information of thecase 100 stored in the use management device 303 in a one-to-one manner,that is, a plurality of pieces of second gaming chip informationobtained by the identifying unit 230 coincide with any one of aplurality of pieces of second gaming chip information associated withthe case identification information of the case 100 stored in the usemanagement device 303 without overlapping, the determining unit 231determines that a plurality of gaming chips C contained in the case 100are pass, and when any one of a plurality of pieces of first gaming chipinformation does not coincide or any one of a plurality of pieces ofsecond gaming chip information does not coincide, the determining unit231 determines that a plurality of gaming chips C contained in the case100 are fail.

As a case in which one of a plurality of pieces of first gaming chipinformation does not coincide with the stored information or one of aplurality of pieces of second gaming chip information does not coincidewith the stored information, there is a case in which any one of gamingchips C contained in the case 100 is a fake or a case in which the RFIDtag 503 or the side surface of the gaming chip C is damaged. In otherwords, the determining unit 231 determines whether or not a plurality ofgaming chips C contained in the case 100 are pass or fail by determiningthe authenticity/damage of all the gaming chips C contained in the case100.

In a fourth pass/fail determination method, the first gaming chipinformation and the second gaming chip information in the same gamingchip C are different information as illustrated in FIG. 16 . In anexample of FIG. 16 , information of an English character string isstored in the RFID tag 503 of the gaming chip C as the first gaming chipinformation, and the designated color layer 501 of the side surface ofthe gaming chip C is colored in the designated color corresponding tothe value as the second gaming chip information.

The RFID reader 221 reads out the first gaming chip information from theRFID tag 503 of the gaming chip C and outputs the first gaming chipinformation to the identifying unit 230, the visible light camera 226photographs the side surface of the gaming chip C and outputs a capturedimage to the identifying unit 230, and the identifying unit 230 analyzesthe captured image and specifies the designated color which is thesecond gaming chip information. In this case, in the identifying unit230, a correspondence relation between a plurality of pieces of firstgaming chip information and a plurality of pieces of second gaming chipinformation is unclear.

The first gaming chip information and the second gaming chip informationare stored in the use management device 303 in association with the caseidentification information of the case 100. The determining unit 231compares a plurality of pieces of first gaming chip information obtainedby the identifying unit 230 with a plurality of pieces of first gamingchip information associated with the case identification information ofthe case 100 stored in the use management device 303 and determineswhether or not they completely correspond to each other in a one-to-onemanner. The determining unit 231 compares the number of each designatedcolor in a plurality of pieces of second gaming chip informationobtained by the identifying unit 230 with the number of each designatedcolor in a plurality of pieces of second gaming chip informationassociated with the case identification information of the case 100stored in the use management device 303, and determines whether or notthe numbers of designated colors coincide with each other.

When a plurality of pieces of first gaming chip information obtained bythe identifying unit 230 completely correspond to a plurality of piecesof first gaming chip information associated with the case identificationinformation of the case 100 stored in the use management device 303, andthe number of each of all the designated colors in a plurality of piecesof second gaming chip information obtained by the identifying unit 230coincide with the number of each of all the designated colors in aplurality of pieces of second gaming chip information associated withthe case identification information of the case 100 stored in the usemanagement device 303, the determining unit 231 determines the case 100to be “pass”, and when any one of a plurality of pieces of first gamingchip information does not coincide, and the number of any one of thedesignated colors in a plurality of pieces of second gaming chipinformation does not coincide, the determining unit 231 determines theplurality of gaming chips C contained in the case 100 to be “fail”.

As a case in which one of a plurality of pieces of first gaming chipinformation does not coincide with the stored information or the numberof any of the designated colors in a plurality of pieces of secondgaming chip information does not coincide, there is a case in which anyone of gaming chips C contained in the case 100 is a fake or a case inwhich the RFID tag 503 or the side surface of the gaming chip C isdamaged. In other words, the determining unit 231 determines whether ornot a plurality of gaming chips C contained in the case 100 are pass orfail by determining the authenticity/damage of all the gaming chips Ccontained in the case 100 and the number of gaming chips C for eachvalue.

In a fifth pass/fail determination method, the first gaming chipinformation and the second gaming chip information in the same gamingchip C are different information as illustrated in FIG. 17 . In anexample of FIG. 17 , the individual identification information includinga numeric string is stored in the RFID tag 503 of the gaming chip C asthe first gaming chip information, and the value information of thegaming chip C is assigned to the side surface of the gaming chip C asthe second gaming chip information in the form of the designated colorof the designated color layer 501.

The RFID reader 221 reads out the first gaming chip information from theRFID tag 503 of the gaming chip C and outputs the first gaming chipinformation to the identifying unit 230, the visible light camera 226photographs the side surface of the gaming chip C and outputs a capturedimage to the identifying unit 230, and the identifying unit 230 analyzesthe captured image and specifies the designated color which is thesecond gaming chip information. In this case, in the identifying unit230, a correspondence relation between a plurality of pieces of firstgaming chip information and a plurality of pieces of second gaming chipinformation is unclear.

The correspondence relation between the first gaming chip informationand the second gaming chip information is stored in the use managementdevice 303. In an example of FIG. 17 , the individual identificationinformation uniquely specifying the gaming chip C is associated with thedesignated color of the designated color layer 501 of the side surface,that is, the value information of the gaming chip C, and it is possibleto understand the value of the gaming chip C when the individualidentification information is designated. In the case of the presentexample, the use management device 303 need not store a combination ofthe first gaming chip information and the second gaming chip informationfor each piece of case identification information. In other words, inthe present example, the gaming chips C contained in case 100 can beinspected without using the case identification information.

The determining unit 231 specifies the first gaming chip informationcorresponding to the first gaming chip information identified by theidentifying unit 230 from the first gaming chip information stored inthe use management device 303 and specifies the second gaming chipinformation associated with the first gaming chip information, that is,the value. The determining unit 231 can obtain the number of each valuein a plurality of pieces of second gaming chip information extractedfrom the use management device 303 for one case by performing the aboveprocess on all pieces of the first gaming chip information identified bythe identifying unit 230.

The determining unit 231 compares the number of each value obtained asdescribed above with the number of each value in the second gaming chipinformation identified for the case 100 from the identifying unit 230.When the numbers of each of all the values coincide, the determiningunit 231 determines that a plurality of gaming chips C contained in thecase 100 are pass, and when the number of any one of the values does notcoincide, the determining unit 231 determines that a plurality of gamingchips C contained in the case 100 are fail.

As a case in which the number of each value in a plurality of pieces ofsecond gaming chip information extracted from the use management device303 does not coincide with the number of each value in the second gamingchip information identified for the case 100 from the identifying unit230, there is a case in which any one of gaming chips C contained in thecase 100 is a fake or a case in which the RFID tag 503 or the sidesurface of the gaming chip C is damaged. In other words, the determiningunit 231 determines whether or not a plurality of gaming chips Ccontained in the case 100 are pass or fail by determining theauthenticity/damage of all the gaming chips C contained in the case 100and the number of gaming chips C for each value.

Although not illustrated, even when the value of the gaming chip C isstored as the first gaming chip information, and the individualidentification information of the gaming chip C is stored as the secondgaming chip information, the pass/fail determination can be performedsimilarly to the above example.

The first to fifth pass/fail determination methods have been describedabove, but the determining unit 231 may employ a combination of theabove pass/fail determination methods. In addition to the abovepass/fail determination methods, when both the number of pieces of firstgaming chip information and the number of pieces of second gaming chipinformation read from a plurality of gaming chips C contained in thecase 100 are not a predetermined number (100 in the present embodiment),the determining unit 231 may determine that a plurality of gaming chipsC contained in the case 100 are fail.

The first and second pass/fail determination methods are pass/faildetermination methods that can be executed without using the informationstored in the use management device 303 installed in the game hall P andsuitable when executed by the inspecting device 200 in the factory F,the third to fifth pass/fail determination methods are pass/faildetermination methods using the information stored in the use managementdevice 303 installed in the game hall P and suitable when executed bythe inspecting device 200 in the game hall P, but the inspecting device200 in the game hall P may employ the first or second pass/faildetermination method. When all the inspecting devices 200 in the gamehall P employ the pass/fail determination method in which theinformation stored in the use management device 303 is not used such asthe first or second pass/fail determination method, the use managementdevice 303 may be omitted.

Further, the inspecting device 200 in the game hall P also inspects thecase 100 containing the used gaming chips C, but in the case, the first,second, or fifth pass/fail determination method in which information ofthe gaming chips to be contained in the case need not be stored may beemployed.

Further, in the above embodiment, the gaming chip C includes theindividual identification information and/or the value information asthe first gaming chip information and/or the second gaming chipinformation. Here, the individual identification information isinformation uniquely specifying each gaming chip C, whereas the valueinformation is information that can overlap each other in a plurality ofgaming chips C and can be regarded as information (group information)indicating a group to which each gaming chip belongs. In the presentembodiment, as the group information of the associated group, instead ofthe value or in addition to the value, for example, information of agaming chip manufacturing time, a manufacturer, and/or a game hall inwhich a gaming chip is used may be employed.

In other words, both the first gaming chip information and the secondgaming chip information may include the individual identificationinformation identifying the gaming chip, the first gaming chipinformation and the second gaming chip information may include the groupinformation indicating the group to which the gaming chip belongs, thefirst gaming chip information may include the individual identificationinformation identifying the gaming chip, and the second gaming chipinformation may include the group information of the group to which thegaming chip belongs, or, the first gaming chip information may includethe group information of the group to which the gaming chip belongs, andthe second gaming chip information may include the individualidentification information identifying the gaming chip.

FIGS. 18 and 19 are diagrams illustrating an example of a pass/faildetermination result display screen illustrating a pass/faildetermination result in the determining unit 231. These pass/fail resultdisplay screens are generated by the computer 222 on the basis of thepass/fail determination result in the determining unit 231 and displayedon the display unit 223. FIG. 18 illustrates an example of a displayscreen in the case of “pass”, and FIG. 19 illustrates an example of adisplay screen in the case of “fail.”

As illustrated in FIGS. 18 and 19 , a pass/fail result display screen800 includes a total of the number of detections 801 which is the numberof combinations of the first gaming chip information and the secondgaming chip information read out from the gaming chip C by theidentifying unit 230, the number of authorized gaming chips C 802, andthe number of unauthorized gaming chips C 803.

The computer 222 sets a larger one of the number of pieces of firstgaming chip information and the number of pieces of second gaming chipinformation as the total of the number of detections 801. For example,when 100 gaming chips C are contained in the case 100, and one of the100 gaming chips C has no RFID tag 503 therein, the identifying unit 230specifies 100 pieces of second gaming chip information from a pluralityof gaming chips C but obtains only 99 pieces of first gaming chipinformation. In this case, the computer 222 sets 100 which is the largerof the first gaming chip information and the second gaming chipinformation as the total of the number of detections 801.

In the case of the first or second pass/fail determination method, thecomputer 222 decides the number of combinations of the first gaming chipinformation and the second gaming chip information that are determinedto coincide with each other as the number of authorized gaming chips C802, and decides a number obtained by subtracting the number ofauthorized gaming chips C from the total of the number of detections 801as the number of unauthorized gaming chips C 803.

In the case of the third or fourth pass/fail determination method, thecomputer 222 decides a smaller one of the number of pieces of firstgaming chip information in which the correspondence relation with thefirst gaming chip information stored in the use management device 303has been confirmed and the number of pieces of second gaming chipinformation in which the correspondence relation with the second gamingchip information stored in the use management device 303 has beenconfirmed as the number of authorized gaming chips C 802, and decides anumber obtained by subtracting the number of authorized gaming chips Cfrom the total of the number of detections 801 as the number ofunauthorized gaming chips C 803.

In the case of the fifth pass/fail determination method, the computer222 decides the number of pieces of second gaming chip information inwhich the correspondence relation with the second gaming chipinformation stored in the use management device 303 has been confirmedas the number of authorized gaming chips C 802, and decides a numberobtained by subtracting the number of authorized gaming chips C from thetotal of the number of detections 801 as the number of unauthorizedgaming chips C 803.

The pass/fail result display screen 800 includes a gaming chipinformation display portion 804 that displays the gaming chipinformation read out from the gaming chip C through the identifying unit230. In the gaming chip information display portion 804, when the gamingchip information stored in the use management device 303 is read or whenthe first gaming chip information coincides with the second gaming chipinformation, the gaming chip information is colored and displayed, andthe gaming chip information which is stored in the use management device303 but not read out is displayed in white (see FIG. 19 ).

In the pass/fail result display screen 800, when the gaming chipinformation not stored in the use management device 303 is read or whenthe first gaming chip information does not coincide with the secondgaming chip information, the gaming chip information is displayedoutside the gaming chip information display portion 804 as unauthorizedgaming chip information 805.

FIG. 20 is a diagram illustrating an RFID antenna 224 of the inspectingdevice 200 according to a modified example. In FIG. 20 , the arm 227,the infrared camera 225, and the visible light camera 226 are notillustrated. In the above embodiment, the RFID antenna 224 is installedin the left and right sidewalls 211, but the RFID antenna 224 may beinstalled in an inner wall 213. In this case, the RFID antenna 224 isarranged in a spiral shape inside the inner wall 213.

FIG. 21 is a side view of a gaming chip C′ according to a modifiedexample. In the gaming chip C of the above embodiment, the designatedcolor layer 501 is sandwiched between the common color layers 502, butin the example of FIG. 21 , in the gaming chip C′, a common color layer502 is formed as the center, and the designated color layer 501 isformed as both (upper and lower) sides. In the example of FIG. 21 ,individual identification information indicated by a 7-digit numericstring is inscribed (printed) on the side surface of the gaming chip C′as code information 505′. In the example of FIG. 21 , the codeinformation 505′ serving as the notation information is inscribed on thecommon color layer 502 in the middle. In this case, the code information505′ can indicate 10-th power of 7 types of information.

Further, both the code information 505 indicated by the presence/absenceof the mark m described for the gaming chip C of the above embodimentand the code information 505′ of the numeric string illustrated in FIG.21 are inscribed on the side surface of the gaming chip C. In this case,the code information 505 of the mark m and the code information 505′ ofthe numeric string may be printed with different types of ink. Forexample, the code information 505 of the mark m may be printed with theinfrared reaction ink, and the code information 505′ of the numericstring may be printed with the UV reactive ink. In this case, aninfrared camera and an ultraviolet camera may be prepared to photographthe side surface of the gaming chip C, the code information 505 of themark m may be read by the infrared camera, and the code information 505′of the numeric string may be read by the ultraviolet camera.

FIG. 22 is a side sectional view of the gaming chip C″ according toanother modified example. The gaming chip C″ has a multi-layer structurein which a plurality of plastic layers having different colors arestacked, a designated color layer 501 (a colored layer) is arranged atleast in the middle, and a common color layer (a white or light-coloredlayer) 502 are stacked on both sides of the designated color layer 501in the middle. It is desirable that the color of the common color layer502 be thinner than the color of the designated color layer 501. Sincethe gaming chip C″ has a multi-layer structure in which the designatedcolor layer 501 is arranged, and the common color layer 502 is stackedon both sides of the designated color layer 501 in the middle asdescribed above, it is possible to specify a type of gaming chip C″ (10points, 20 points, 100 points, 1,000 points, or the like) by forming astripe pattern on the side surface in a stack direction and changing thecolor of the designated color layer 501 (red, green, yellow, blue, orthe like) as illustrated in FIG. 23 .

FIG. 23 is a perspective view of stacked gaming chips C,″ FIG. 24 is aside view of the gaming chip C″, and FIG. 25 is a plan view of thegaming chip C.″ As illustrated in FIG. 23 , the gaming chip C″ has afive or more-layer structure in which a print 507 (100 points or thelike) indicating a type (value) of gaming chip C″ is performed on thesurface (the upper surface and the lower surface) of the common colorlayer 502, a transparent layer 504 is formed as the outermost layer, andthe respective layers are thermocompression-bonded. The gaming chip C″is formed using an elongated plastic material such that a state in whichthe respective layers (the designated color layer 501, the common colorlayer 502, and the transparent layer 504) are thermocompression-bondedand adhered to each other in an elongated stated (a five-layer structureor the like) is formed and then punched out into a circular shape, arectangular shape, or the like through a process or the like. When thepunching is performed through the press, dimensions of a die and a punchof a mold for punching are designed, and R treatment (rounded corner) isapplied to the end of the transparent layer 504 of the outermost layer.

Further, in the gaming chip C,″ the mark m″ is formed on the surface ofcommon color layer 502 using the UV ink or the carbon black ink. Themark m″ indicates whether the gaming chip C″ is true or false, and themark m″ becomes visible when irradiated with ultraviolet rays (orinfrared rays), and it is indicated whether the gaming chip C″ is trueor false in accordance with a combination of shapes of the mark m″ andthe number of marks m″. The transparent layer 504 is thermocompressionbonded or applied on the outermost layer so as to cover the print 507 orthe mark m′, but embossing treatment is applied to the transparent layer504, and thus the gaming chips C″ are prevented from adhering to eachother.

The R treatment (R) is performed on the end of the transparent layer 504of the outermost layer which has undergone a print 507 (100 points orthe like), and the surface of the common color layer 502 is preventedfrom being deformed in the process of punching the gaming chip C″ andappearing on the side surface. Further, a sharp edge of the gaming chipC″ is prevented from remaining and damaging a hand and other gamingchips C″.

As illustrated in FIG. 22 , the designated color layer 501 may be formedby a plurality of layers colored in the designated color (three layersin FIG. 22 ). Since a plurality of layers colored in the designatedcolor (three layers in FIG. 22 ) are thermocompression bonded to eachother, the three-layer structure is not visible as illustrated in FIG.22 , and FIG. 22 illustrates the three layers of the designated colorlayer 501 for the sake of description. Further, a partial hollow B isformed in a middle layer among the three layers of the designated colorlayer 501, and a RFID tag 503 is installed in the partial hollow B.

Since the gaming chip C, C′, and C″ have a stacked multi-layerstructure, and a stripe pattern in the lamination direction is vividlyformed on the side surface as illustrated in FIG. 2 , FIG. 21 , and FIG.22 , it is possible to easily and accurately measure the color of thedesignated color layer 501 (the type of gaming chip) and the number ofdesignated color layers 501 through image analysis as compared with achip of a related art. FIG. 26 is a diagram illustrating an example ofan image obtained by photographing the stacked gaming chips. Asillustrated in FIG. 26 , it is possible to photograph the side surfaceof the gaming chip C through the visible light camera 226 and clearlyidentify the designated color layer 501. Further, it is possible toaccurately analyze and determine an image when an artificialintelligence utilization type computer or control system or a deeplearning (structure) technique is used in the image analysis. Since theartificial intelligence utilization type computer or control system orthe deep learning (structure) technique is known to those skilled in theart, detailed description thereof is omitted.

As described above, the case 100 is sealed with a seal after apredetermined number of gaming chips C are contained. The seal is brokenwhen the case is opened to allow the contained gaming chips to bewithdrawn. The inspecting device 200 may include a detecting unit thatdetects an unbroken seal affixed to the case 100. The detecting unit maydetect the seal optically or magnetically. In this case, when anunbroken seal is not detected by the detecting unit, the determiningunit 231 determines that a plurality of gaming chips C contained in thecase 100 are fail.

In the above embodiment, all the components of the inspecting device 200are arranged in a single device as illustrated in FIG. 6 , but thecomponents may be distributedly arranged. For example, some or all ofthe computer 222, the display unit 223, and the communication unit 229may be implemented by a personal computer connected to the inspectingdevice 200. The distributedly arranged components may be connected to beable to perform wired or wireless communication or may be connected viaa network such as the Internet.

Further, as illustrated in FIGS. 27 and 28 , the infrared camera 225and/or the visible light camera 226 and the arm 227 may be separatedfrom the inspecting device 200, and the cameras may be connected to thecomputer 222. FIG. 27 illustrates an example in which only one of theinfrared camera 225 and the visible light camera 226 is installedseparately from the inspecting device 200, and FIG. 28 illustrates anexample in which the infrared camera 225 is installed separately fromthe inspecting device 200, and the visible light camera 226 is installedintegrally with the inspecting device 200. Further, in addition to theinfrared camera 225 and the visible light camera 226, an ultravioletcamera may be installed as a third camera together with an ultravioletlamp, or one of the cameras in FIGS. 27 and 28 may be an ultravioletcamera equipped with an ultraviolet lamp.

In the above embodiment, in the gaming chip C, the gaming chipinformation is stored in the RFID tag 503, the code information 505serving as the gaming chip information is inscribed on the side surface,the designated color of the designated color layer 501 of the sidesurface is also dealt as the gaming chip information indicating thevalue of the gaming chip C, and one gaming chip C has the three piecesof gaming chip information, but the present invention is not limited tothis example, and the gaming chip C may has only two of the three piecesof gaming chip information. When the gaming chip C has two pieces ofgaming chip information, the first to fifth pass/fail determinationmethods can be executed.

In the above first to fifth pass/fail determination methods, two piecesof gaming chip information are used, but when the gaming chip C hasthree pieces of gaming chip information, the determining unit 231performs the pass/fail determination using the three pieces of gamingchip information.

In the above embodiment, the example in which the display unit 223 isconfigured with a liquid crystal panel has been described, but thedisplay unit 223 may be a lamp that simply indicates only whether it ispass or fail or may be a lamp that performs digital display of the totalof the number of detections 801, the number of authorized gaming chips C802, and the number of unauthorized gaming chips C 803.

The determining unit 231 of the above embodiment is able to specify thenumber of each of the values of a plurality of gaming chips C containedin the case 100 as described above. In this regard, the determining unit231 may further calculate a total amount of the values of a plurality ofgaming chips C contained in the case 100 on the basis of the number ofeach value. The calculated total amount may be displayed on thepass/fail result display screen (see FIGS. 18 and 19 ) displayed on thedisplay unit 223.

A second embodiment relates to an inspection system and an inspectingdevice which are capable of inspecting the gaming chips, and moreparticularly to, an inspection system and an inspecting device which arecapable of inspecting the gaming chips having a radio tag embeddedtherein or counting the number of gaming chips.

A gaming chip having a radio tag storing identification information ortype information therein is known (for example, JP 2008-246103 A).

A gaming chip having a structure in which a radio tag is not easilyextracted is disclosed in JP 2008-246103 A. Accordingly, a structure inwhich the radio tag hardly has a defect is implemented.

However, when the number of gaming chips disclosed in JP 2008-246103 Ais read by the radio tag, since the number of gaming chips is calculatedon the basis of the read radio tag information, gaming chip informationis unable to be acquired when the radio tag installed in the gaming chipis broken or when no radio tag is installed, and there is a problem inthat there is a difference between the actual number of gaming chips andthe number of gaming chips calculated by reading the radio tag.

In this regard, it is an object of the present invention to provide aninspection system and an inspecting device which are capable ofdetecting whether or not the radio tag is broken.

An Inspection system according to a first aspect of the secondembodiment is an inspection system that inspects gaming chips eachhaving a color or a display indicating a value on an outer surface in astate where the gaming chips are stored in a case in which a maximum ofthe number of gaming chips to be stored is limited, a radio tag storinggaming chip information being embedded in each of the gaming chips, thegaming chips being stored in the case capable of containing a row ofgaming chips stacked in a thickness direction, the inspection systemincluding: a reading device that reads the radio tag of the gaming chipin the case and acquires gaming chip information of the gaming chip; anda determining unit that compares the gaming chip information acquired bythe reading device with a maximum of the number of gaming chips storablein the case and determines an abnormality of the gaming chip in the casewhen the number of gaming chips obtained from the gaming chipinformation acquired by the reading device is different from a maximumof the number of storable gaming chips.

Further, the determining unit has a function of comparing a physicalcharacteristic of the case or physical information of the gaming chipobtained from a physical measurement means other than the reading devicewith the number of pieces of physical information of the gaming chipobtained from the gaming chip information acquired by the readingdevice, determining that there is an abnormal gaming chip among thegaming chips contained in the case when both pieces of information donot coincide with each other, and outputting a determination result.

Further, the physical information is a number or height which isobtained optically or a weight which is obtained by measurement.

Further, the inspection system may further include a radio taginformation database which is able to refer to information of the radiotag embedded in the gaming chip, and the determining unit may beconfigured to compare the gaming chip information of the gaming chipread by the reading device with the information of the radio taginformation database and detect an abnormality of a gaming chip of aninspection target.

Further, the determining unit may have a function of comparing, when itis determined that there is an abnormal gaming chip among the gamingchips in the case, the information of the radio tags of all the gamingchips in the case with the radio tag information database registered inadvance and specifying the presence of an abnormal radio tag which isnot stored in the radio tag information database.

Further, the determining unit may have a function of specifying, when itis determined that there is an abnormal gaming chip among the gamingchips in the case, the presence of an abnormal gaming chip in whichinformation from the radio tag is unable to be obtained among the gamingchips in the case.
